computNPA fails when the input data.frames don't have the same number of rows

computNPA fails with an uninformative error when the number of rows in the data.frames of the input list dL is not the same.

The function checks the order of nodeLabel, but doesn't fail, here. Rather it fails when computing s, here

@MahShaaban, this is correct. I will add some check of the rows of the different slots. Actually, they have to be the same across the slots, so if different, the intersection has to be used.

Thanks @sgubianpm
Yes. To get the function to work, I used the intersection of the slots as you point out.
It would be great if the function can do that automatically, possibly with a warning. Or, the function could fail with an informative error message.
